HEATING ATTACHMENT FOR MOTOR-VEHICLES.

drawings, forming a part of this specification, and to the reference-numerals marked thereon.

'My invention relates to heating attachments for motor vehicles, and it has for its object to provide a device that may be read-v ily applied to any of the well known types of automobiles, and which is adapted to obtain its supply of heat from the exhaust gases of the engine, in a manner which makes the device both efficient and practical.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a longitudinal, vertical sectional view of a portion of an automobile, showing the application of a preferred embodiment of my invention; Fig. 2 is a vertical sectional view of the heating box; Fig. 3 is a view in end elevation o fth'e exhaust pipe outlet; Fig. t is a side elevation of the rear end of the exhaust pipe; Fig. 5 is a sectional view of the same,

slm lar reference numerals throughout the several figures indicate the same parts.

In the embodiment of the invention as ,herein illustrated, A designates the body of the vehicle which is provided with an explosive engine, as usual in this class of machines, and which I deem it unnecessary to show in the present drawings.

B is the exhaust pipe for conducting the exhaust gases from the engine, within which pipe is interposed a muflier G which may be of any well known construction.

In order to take advantage of the heat of the exhaust gases at sufficiently low pressure to obviate any undesirable effects, such as an explosion in the heating box, I conduct the gases to the heater after they have passed through the mufiler, means being pro- Specification of Letters Patent.

vided for permitting them to exhaust directly to the atmosphere when the heater is not in use. To this end, the rear end of the exhaust pipe B is provided with a coupling 1 having an outlet 2, and connected thereto is a branch pipe preferably arranged vertically, and leading to a heating coil iwhich is arranged in the heating box the opposite endof said coil being connected to an outlet 6.

7 is a gate valve which is pivotally mounted in the coupling 1, and arranged to close the outlet 2 while permitting communication between the exhaust pipe and the branch pipe 3. The valve 7 carries an arm 8 to which is secured a connection designatedat 9, which is guided about the pulleys 10 and provided at its forward end with a ring or other suitable attaching means 11 by which it may be held in engagement with a hook 12. The connection 9 embodies a yieldable portion, preferably in the form of a coil spring 13, the purpose of which is to permit the valve 7 to open ,in an emergency, as for instance if an explosion should occur in the muflier G. Then the valve is closed, or in some manner an excessive or dangerous pressure is produced. Then it becomes necessary to relieve the pressure quickly, to prevent it from entering the heater which would thereby be damaged, and, under such conditions, the connection 9'yields sufliciently, under the sudden impact of the pressure against the valve 7, to permit the valve to open and afford a direct passage to the atmosphere. When it is desired not to use the heater, the fastening member 11 is disconnected from the hook 12, permitting the valve to drop down and open the exhaust outlet.

. ably provided with a series of openings 16 which are controlled by damper l? slidably arranged'with relationto the openings 16, and adapted to be controlled by a handle 18. By opening the damper 17, the heating box may be supplied with a suitable amount 01%, fresh air, and when the vehicle is moving fast, or other conditions exist which would pipe from the engine, of a heater, a branch cause an excessive flow of cold air into the heating box, the damper may be closed or adjusted.

The invention is susceptible of various changes and modifications without departing from the essential features outlined herein, and it is to be understood that I intend to cover bythis application any departure from the specific structure shown and described that may come Within the terms of the claims hereinafter.

' I claim as my invention: 1. In a heating attachment for motor vehicles, the combination with the exhaust pipe from the engine, of a heater, a branch pipe leading from the exhaust pipe to the heater, a valve controlling the outlet of the exhaust, a muflier interposed in the exhaust pipe in advance of said valve, and yieldable means for holding the valve closed.

2. In a heating attachment for motor vehicles, the combination with the exhaust plpe interposed slightly in advance of the outlet of the exhaust pipe and leading to the heater, a valve arranged to shut off the outlet of the exhaust pipe, a mufiler arranged in advance of said branch pipe, and a yieldable connection extending from the valve to the body of the vehicle by Which the valve maybe opened, or held yieldably in closed position.

3. In a heating attachment for motor vehicles, the combination With the exhaust pipe from the engine having an outlet at its rear end, of a heater, ,a branch pipe ining to said heater, a valve arranged to close the outlet and to divert'the gases into said branch pipe, a muffler arranged in advance of the branch pipe, and yieldable meansacting to hold the valve normally so as to close the outlet of the exhaust pipe. v

4. In a heating attachment for motor vehicles, the combination With the exhaust pipe from the engine, a mufller therein, a deflecting valve beyond the mu'filer near the outlet end of the exhaust pipe, a heater, a pipe connecting said heater with the valve",

*- a manually operable elastic connection for moving the valve into position to deflect the hot exhaust gases from the engine into said heater pipe, and-to maintain it resiliently in its deflecting position, said heater comprising a register adapted to be positioned inthe floor of the vehicle and constructed to form air openings of fixed dimensions, and air inlet ports, and an adjustable damper arranged to control" the air inlet ports,
